MPG AUDI S4 SEDAN 2013 Owners Manual

Trip computer
Introduction
Applies to vehicles: with trip computer
The trip computer gives you information on
current and average fuel mileage, average
speed, fuel range and driving time .
Fig. 9 Trip comp uter d isp lay : Ave rage fuel mileage
The following information is continuously
eva luated by the trip computer and can be dis­
played sequentia lly in the instrument cluster
disp lay:
Fuel range
The estimated cruising range in miles (km)
appears in the display. This tells you how far
your vehicle wi ll be able to travel on the cur­
rent tank of fuel and with the same driving
style. The display changes in increments of 6
miles (10 km).
The cruising range is calcu lated based on the
fuel consumption for the last 18 miles
(30 km). If you drive conservatively, the cruis­
ing range will increase.
Average fuel mileage
The average fuel economy in MPG (l/100 km)
since you last cleared the memory appears in
this display. You can use this disp lay to adjust
your driving technique to achieve a desired
mileage.
Current fuel mileage
The instantaneous fuel consumption in miles
per gallon (l/100 km) is shown in this disp lay.
You can use this display to adjust your driving
technique to achieve a desired mileage.
Driver information display 25
Fuel consumption is recalculated at intervals
of 33 yards (30 meters). This display switches
to gallons/hour (liters/hour) when the veh icle
is not moving .
Average speed
The average speed in mph (km/h) s ince you
last reset the memory appears in the display.
Elapsed time
The length of time that yo u have been driving
s inc e you last reset the memory appears in
this display.
Distance
The distance that has been covered since the
last time the memory was cleared appears in
the display.
(0 Tips
- Fuel consumptions (average and cur ­
rent), range and speed are displayed in
metric units on Canadian models.
- All stored values will be lost if the vehi­
cle battery is disconnected.
Memories
App lies to vehicles: wi th trip computer
The trip computer is equipped with two fully
automatic memories as well as an efficiency
program*.

You can switch between the trip computer 1
and 2 and the efficiency program* by pressing
the
I RESET I button @c::> page 26, fig. 11 .
You can tell which memory leve l is currently
active by the number or the sign in the display .,..

necessary to keep the vehicle from
rolling.
- If the selector lever is unintentionally
moved into N while you are driving, take
your foot
off the accelerator pedal and
wait for the engine to return to idle
speed before selecting a driving position .
- Never shift into R or P when the vehicle is
in motion .
- Never get out of the driver's seat when
the engine is running.
- If you must get out of the vehicle, move
the selector lever securely into the P po­
sit ion and apply the parking brake firmly.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood . Make sure the
selector lever has securely engaged and
is locked in P with the parking brake
firmly set ¢
page 208, Engine compart­
ment.
Otherwise, any increase in engine
speed may set the vehicle in motion,
even with the parking brake applied.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv­
er 's safety belt is engaged in the buckle.

Transmission 85
The selector lever position engaged appears
next to the selector lever as well as in the in­
strument cluster display .
P -Park
In this selector lever position the transmis­
s ion is mechanically locked. Engage P only
when the vehicle is
completely stopped ¢ &
in Driving the automatic transmission on
page 84.
T o shift in or out of position P, you must first
press and hold the brake pedal and then press
the re lease button in the selector lever handle
while moving the selecto r lever to or from P.
You can shift out of this position only with the
ignition on.
R- Reverse
The transmission will automatically select the
lowest gear ratio when you shift into reverse.
Select R only when the vehicle is at a
full stop
and the engine is running at idle speed ¢ & in
Driving the automatic transmission on
page 84.
Before you move the selector lever to R, press
both the button in the handle of the selector
lever
and the brake pedal at the same time .
When the ignition is on, the backup lights illu­
minate when the selector lever is moved into
R.
N -Neutral
The transmission is in neutral in this position.
Shift to th is position for standing with the
brakes applied ¢
page 86.
When the vehicle is stationary or at speeds
below 3 mph (S km/h), you must always apply
the footbrake before and while mov ing the
lever out of N.
D /S -Normal position for driving forward
In the D/S pos ition, the transmission can be
operated either in the normal D mode or in
the S sport mode . To select the S sport mode,
pull the selector lever back briefly . Pulling the
lever back again will se lect the normal D ...,

(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
.,. Have your vehicle serv iced at regular inter-
vals .
By having your vehicle regularly serviced by an
authori zed Audi dealer helps to ensure that it
runs properly and economically . The condition
of your vehicle not only affects its safety and
ab il ity to hold its value, it also affects
fuel
consumption.
Check your oil each time you fill your tank.
The amount of oil used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3 ,000 miles
(5,000 kilometers) before you can properly
assess oi l consumption.
This a lso applies to fuel consumption and en­
g ine output .
0 Note
-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte ­
nance as well as improper use of the ve­
hicle will impair the function of the
emission control system and could lead
to damage.
Driving and environment 195
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer .
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents .
Fewer short trips
Fuel consumption will always be rela tively
high on short trips .
.,. Try to avoid driving short distances with a
cold engine.
The engine and cata lytic converter have to
reach their opt imal
operating temperature to
reduce fuel consumpt ion and noxious emis­
sions effectively .
Just after starting, a co ld engine in a mid-size
car only achieves a fuel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km) . After about
2 .5 miles (4 km),
the engine is at its proper operat ing tempera­
ture and fuel economy has reached a normal
level. So you can see that you should avoid
short trips whenever possible.
T he
outside temperature is also cr itical in th is
regard. Your car consumes more fue l in the
winter than in the summer.
